Introduction

What is NAS?

NAS is short for “Network attached Storage”, which is used to name a specialized device that offers mass storage towards a data network. SOHO NAS like the ICY BOX IB-NAS4220-B are small devices that simply share data from HDDs to an Ethernet. There are many approaches; some are using custom shaped methods in offering the storage space to the network participants. This approach needs special software to be installed on the network clients and in most cases is limited to one particular operating system.

The ICY BOX IB-NAS4220-B has chosen to offer the HDD space in the way common operating systems are expecting it. This means it uses the same principles (protocols) to offer HDD-Storage as common file servers are doing it but with less noise, lower power consumption and in a much simpler way. The main advantage is that, that special software is unnecessary to access the storage provided, whilst maintaining the maximum security features, as already offered within the operation system, such as user and group based access control.

Samba (Windows)

Network

The samba server implemented in the ICY BOX IB-NAS4220-B offers storage in a way regular Windows shares are doing it (commonly known as SMB or CIFS protocol). Even operating systems like MAC OS and Linux are capable of using this kind of network storage access. It provides a maximum of security by offering the opportunity to limit the access on users or groups.

4

Manual IB-NAS4220-B

FTP

The FTP protocol is one of the oldest ways for file transfer in the internet. It is fast and could easily be used to access the HDD even via the internet. A huge set of different software clients exists even for exotic operating systems using this simple but fast protocol. Most internet access routers used in small offices and at home offer a mechanism called port forwarding (virtual server, etc.) which could be easily used to expose the ICY BOX IB-NAS4220-B’s storage to the internet. The FTP protocol offers access control based on user and groups.

NFS

In the Unix world the NFS protocol is common to share disk space via network. This protocol could be used to mount natively network storage to all kinds of Unix operating systems like Linux, Solaris, etc. The NFS protocol is fast but does not provide a User or Group based access control server sided. Access control is limited to the definition of singular or a set of IP-Addresses (host addresses).

More than a NAS

But the IB-NAS4220-B is more. You can print via Network or if you want to access to your music, pictures or video files by using your network at home the UPnP-AV protocol offers a communication mechanism for your network media player to access all media files on the IB-NAS4220.

year so far to ensure compatibility to all new players. Therefore we have chosen to not implement this software fix in the firmware of the IB-NAS4200-B but to give the user to easily upgrade it when a new version is released. A permanent license can be purchased from the Website of Twonky Media by following a link from the user interface of Twonky Media.

Bonjour and iTunes Support

Network

The IB-NAS4220 is able to assign its services via Bonjour, so that MAC computer can easily be connected to the server functions of the IB-NAS4220-B. Due to the iTunes support, multimedia files can be accessed via iTunes from anywhere in the network.

7

Manual IB-NAS4220-B

BitTorrent protocol Support

The IB-NAS4220-B has an integrated BitTorrent protocol client. So you can download data via the peer to peer Network without a running PC. The IB-NAS4220-B consumes much less electricity compared to a conventional PC. This protects the environment and saves money.

What is RAID?

RAID is short for “Random Array of Inexpensive Disks”. It names a way of using several hard disks intelligently together, in order to improve security or speed or to combine their disk space. RAID is divided in levels. These levels, designated by a number, are indicating each a certain strategy to combine disk space. Each strategy has different advantages for the user. The IB-NAS 4220-B offers the following RAID levels:

RAID 0 (Stripe Set)

RAID 0 writes data block wise alternating on the two disks. So two data blocks can be written at the same time, which enhances speed. The disk space of the combined volume is twice the smaller disk size. If one drive fails, all data is lost. In reality, this level grants

no speed increase on the IB-NAS4220-B because other limitation factors are responsible for the network performance than the drive access.

RAID 1 (Mirroring)

Disc 2 Disc 1

In RAID 1 mode all data is written identically on both discs. So if one disc fails the other contains all data again. This provides security against the failure of one disk at the cost of the bigger disks space.

Attention: If you choose RAID 1, please mind, that it is not a good strategy to use two hard discs of the same type and from the same product line. If the machine which produced the hard discs was defect, it is very likely that all hard discs produced by that machine are defect. If both discs fail, all data will be lost, because RAID 1 does not help against the simultaneous failure of both discs.

Manual IB-NAS4220-B

disks are added to one big disk. Because RAID 0 does not offer a real speed increase Spann should be preferred.

JBOD

JBOD is short for “Just a Bunch Of Disks”. Like Spann it is not really a RAID mode. This means that both discs are integrated as separate hard drives with its own content, independent from each other.

How to access the management interface The NAS modus is controlled by a web based interface which could be accessed by using a standard web browser. In a normal network environment this is simply done by entering “http://IB-NAS4220-B” in the address line of the web browser. But whether that works is determined by the configuration of the network environment.

The following Possibilities are given:

DHCP controlled Network with automatic DNS update

In a DHCP1 controlled Network the ICY BOX IB-NAS4220-B is assigned with an IP Address2 by the DHCP server. In case the DHCP server updates this information automatically to the DNS3 Server (see RFC 2136). The ICY BOX IB-NAS4220-B could be accessed by simply entering “http://IB-NAS4220-B” in the address line of a standard web browser. Continue with point “Using the management interface” for setting up the IB-NAS4220-B on Page 18.

1 DHCP acronym for “dynamic host configuration protocol” names a process witch assigns network parameters to a computer attached towards a network automatically via a specialized DHCP server. Most DSL routers provide such a service. 2 IP-Address is a 32 bit binary number mostly expressed by a group of four numbers in the Range between 1 and 255 separated by “.” e.g. 169.254.100.100. This is used for addressing hosts in a TCP/IP based Network. 3 DNS is the acronym for “domain name service”. This names a process of assigning internet names to IP Addresses. The DNS server is comparable to a telephone book. At this server all internet applications look up the referring IP Address for an internet name. Without that service or when the DHCP server doesn’t know the internet name, the internet name could not be used to address a host or device. The only chance to get access to that host or device is to use the IP Address directly.

13

Manual IB-NAS4220-B

DHCP controlled Network without automatic DNS update

In a DHCP1 controlled Network environment the IB-NAS4220-B gets its IP Address from the DHCP server. If the DHCP server does not update that information to the DNS server the necessary name resolution for entering “http://IB-NAS4220-B” will not work because the DNS server has no information about the actual IP Address of the IB-NAS4220-B. To find out the IP Address you can turn on the UPnP Support in Windows or use the “SearchNAS.exe” Program on the CD to find out the IP Address.

Click on „Setup“

Select “Exit”

The actual IP Address of the IB-NAS4220-B is displayed

IB-NAS4220-B is found

To access the web management surface enter “http://<IP Address>” in the address line of the Standard Web browser, where <IP Address> is the IP Address found by SearchNAS.exe as described above. Continue with point “Using the management interface” for setting up the IB-NAS4220-B on Page 18.

14

Manual IB-NAS4220-B

Not configured Network / Direct Attachment

If the IB-NAS4220-B is attached to a not configured network where no DHCP server provides the IP configuration (or the IB-NAS4220-B is directly attached to the computer) and the computers are configured to use DHCP (which is default setting) the IB-NAS4220-b will activate its own DHCP Server with the default IP Address 192.168.0.1 and will provide IP Addresses in a range from 192.168.1.2 till 192.168.1.50 with a net mask4 of 255.255.255.0, which is part of the subnet5 192.168.1.1-192.168.1.254. In this case the IB-NAS4220-B can be reached by typing “http://192.168.1.1” in the address line of a standard web browser.

Network configured on fix IP-Addresses

In a network where no DHCP Server is present and all IP-Addresses are configured manually and fixed for example between 192.168.1.1 and 192.168.1.254 with 255.255.255.0 as net mask, 192.168.1.1 as default gateway6 and 192.168.1.1 as DNS server you have to define the IP Address of the IB-NAS4220-B also manually.

To configure the IP Address of the IB-NAS4220-B to for example 192.168.1.100 please start the SearchNAS.exe on the CD and proceed as follows:

Attention: If you are unable to run SearchNAS.exe on your computer because you are not using a Windows operating system please configure the IP-Address of the IB-NAS4220-B using the web configuration interface as described in point “LAN Setting” on page 55.

Click on „Setup“

4 The net mask defines which part of the IP Address is describing the subnet. Together with the IP Address it is the minimum necessary part of the network configuration. So it always has to be set appropriate. 5 TCP/IP based networks, as the internet, are structured into different network parts called sub nets. A subnet is built by a set of IP Adresses all having the same digital beginning. Remember: an IP Address is always interpreted as 32 bit binary number containing 32 binary digits. IP Adresses of the same subnet all have the left part of these digits in common. How many of those digits are used to define a subnet is described by the net mask. Computers in the same subnet are able to communicate directly together. Computers in different subnets need a so called router which connects different subnets and forwards the net traffic from one subnet into another. 6 In a TCP/IP based Network a computer can send data directly only to other computers in it’s own subnet. To be able to send data to other computers, a rooter is necessary to link this subnet to the rest of the network. All computers in the subnet need to know its IP Address because they will send all data for destinations out of their subnet to the rooter to be forwarded. This IP Address of the router is defined by the default gateway setting.

Chosen items are highlighted in white color when selected.

Hard disk initialization The first step in the setup of the IB-NAS4220-B should be the initialization of the hard disk. This is necessary because the IB-NAS4220-B saves some settings in specialized system partitions on the hard disk.

Initializing the hard disk, three partitions are created and formatted on the hard disk:

Attention: The IB-NAS4220-B needs this particular structure of the hard disk in order to be able to operate as NAS. In order to be able to use the IB-NAS4220-B appropriately it is always necessary to proceed this step using the “Disk Utility” dialogue, described on page 23.

Choosing the appropriate RAID level

As described in point “What is RAID?” on page 8 the IB-NAS4220 is able to organize its discs in different RAID levels. These RAID level can provide more security, flexibility or more disc space. In order to enable you to choose the best level for your purpose the following table lists the pros and cons of each level:

RAID level Pros Cons

JBOD • Flexible • Single disc possible • Encryption possible

• Inefficient use of disc space

• Second disc is open to everybody in the network

RAID 0 (not recommended) • Disc space double of the smaller disk

• Less secure, because if one disc fails all data is completely lost

RAID 1 • Very secure • Just the capacity of the smaller disc used

SPAN • Disc space of both discs is added up.

• More secure then RAID 0, because data might be reconstructed with special tools if one disc fails

• Just single security

The choice of the RAID level depends also about which file system7 you want to use and which features. For details about the file systems see point “Choosing the appropriate file system” on page 21.

RAID level File systems Features

JBOD • EXT2 • EXT3 • FAT32

• Encryption

RAID 0 (not recommended) • EXT2 • EXT3

RAID 1 • EXT2 • EXT3

SPAN • EXT2 • EXT3

7 A file system describes the way an operating systems stores data to a mass storage device. A file system may include mechanisms for data organization, naming of files, access control, and system crash stability. Since mass storage management is a very important task to an operating system, a file system is deeply related to its abilities. Different operating systems are orientated to different kinds of file systems and there philosophy.

Manual IB-NAS4220-B

JBOD Setup

If you choose to organize the disks in JBOD mode then you will find the description of the setup in point “Disk Utility” on Page 23.

RAID Setup

If you choose to organize the disks in another RAID mode you will find the description of the setup in point “RAID Setting” on page 27.

Choosing the appropriate file system

In opposite to many other SOHO NAS products at the IB-NAS4220-B you can choose the file system the IB-NAS4220-B uses. The File systems have different pros and contras. Yo have the ability to choose and adapt the IB-NAS4220-B best to your purposes. The data partition of the IB-NAS4220-B could be set up using three different file systems:

File system Description

EXT2 Linux file system

EXT3 Linux journaling file system

FAT32 Windows file system

These file systems differ in the native ability of different operating systems to access them directly (without NAS, this might be interesting when the NAS controller is defect), in their features and limits. That is the reason why no particular file system is preselected for the data partition. Depending on the future use of the IB-NAS4220-B the user can choose the appropriate one.

The “Refresh” button causes a refresh of the displayed data if the display should not be actualized automatically.

At least one disk needs to be initialized in order to let the IB-NAS4220-B appropriately as NAS. The disc formatted first by using the “Disk Utility” dialogue becomes the system disk. If the second disk is formatted using this dialogue too, it will become data disk, which will be accessible to anybody in the network by Samba, FTP or NFS with no access control. If the Second disc is preformatted with EXT2, EXT3 or FAT32, it will be made accessible as described in the sentence before and no initialization is necessary.

Initializing the hard disk is done in three steps: First, select if the hard disc should be encrypted and enter a Password (exactly 20 characters, when prompted), second, choose a file system for the data partition and third, click on “Format” button:

Attention: The choice of the file system has big influence on the features provided by the NAS. Also important is the fact that not all file system types could be read by every operating system. This is of great importance when you plan to use a disc inside the IB-NAS4220-B and also inside a computer. For details see point “Choosing the appropriate file system” on page 21.

Attention: If “encryption” is selected, it will not be possible to read the hard disk information, when the disc is directly attached to a computer. In addition, it will not be possible to read the disk inside the IB-NAS4220-B if the password is lost. Encryption can just be chosen for EXT2 file system.

Attention: Formatting the hard disk will erase all data on the hard disk. Please save all data on it before proceeding to format it!

Removing a RAID array

Attention: Removing a RAID array will erase all data on the hard disk. Please save all data on it before proceeding to format it!

To remove the RAID array click on “Remove raid system”

Please confirm the security warning with “OK”

After the removal of a RAID array, the IB-NAS4220-B will boot again as described above.

Hard disc failure in RAID 1

RAID 1 provides security against data loss if one of the two hard disks fails. The defect hard disk can be replaced by a new disk. The auto rebuild function of the IB-NAS4220-B will copy all data on the new disk again and reestablish the RAID array.

Attention: The new disc (replacing the defect one) has to be as least as big as the old one, but can be bigger.

Attention: Please mind, that if one disc has a failure, you have only one disk left where the data is stored on. This means if that disc fails too, all data will be lost. So to provide maximum security it is recommended to replace the defect disc as soon as possible.

Attention: If the IB-NAS4220-B declares a disc to be defect, please consider this disc to be defect and replace it for sure. The error of the disc might not be in the beginning of the disc, and if you use the defect disc again, the IB-NAS4220-B might not recognize the error when rebuilding the RAID array, but the error might still be there. This can lead to a complete data loss!

File server, share and printer management In this section it explains, how the disk space is provided to the network how a printer is attached to the IB-NAS4220-B, and how this is controlled. The Web interface divides this management into three logical parts. Global server settings, share orientated settings and printer server settings.

File Server Settings

What is a file server? – A file server offers disk space to a network. The term server used to name a service offered to the network. As described in point “What is NAS?” (Page 4) the IB-NAS4220-B uses 3 different services to provide hard disk space to the network: Samba (Windows), FTP and NFS. The basic settings regarding these 3 services are done in the “File Server” item of the “File” submenu.

Control Panel File and Print

File Server

All three servers could be disabled separately. The “File Server Setting” form is structured into 4 parts:

Section Description

Windows Setting basic settings for the Samba service

FTP Server Setting basic settings for the FTP service settings

NFS Server Setting basic settings for the NFS service

Guest Access Setting basic settings for the cross services guest account

Samba basic settings

Guest account settings

NFS basic settings

FTP basic settings

By enabling the “Enable” checkmark for each section the corresponding service is enabled or disabled. By default all services are enabled to grant a rapid start up.

45

Manual IB-NAS4220-B

Windows Setting

As described in point “Samba (Windows)” (page 4) the Samba server provides the storage for Windows clients, also MAC OS and Linux computers are able to use network storage via this service. It has the most complex structure and provides the most features. Therefore the basic settings are a little more extensive, than those for the other services.

Windows offers possibility to structure network participants in so called “Workgroups”. Via this identifier – which is just a name – it gives the opportunity to assort logical units of network participants to give a better overview. This could be set up in the referring field on the form. Also you can enter a description term which will be displayed when browsing11 the windows network. If the windows network has a WINS12 server for providing a network directory, the IP Address could be specified here.

FTP Server Settings

Aside of the possibility to enable or disable the FTP service, the port13 number of that server could be modified in order to accommodate a possible port forwarding14 of a internet access router which uses NAT15, for example if it is desired to make two IB-NAS4220-B accessible via port forwarding by an internet access router.

Attention: Changing the FTP servers port from 21 (default) to another value will cause, that standard FTP client will not be able to access the IB-NAS4220-B FTP server, except the changed port number is configured in the FTP client appropriately.

NFS Server Setting

Here the NFS Server can be enabled or disabled.

11 Browsing signifies here a process of Windows to discover and display network participants. 12 WINS is an acronym for “Windows Internet Naming service”. Windows knows two ways of name resolution (process of assigning IP Addresses to IP Addresses) one is a broadcast based mechanism and the other is WINS, where some network participants take over the role of a directory server called WINS server, registering names and services of other network participants. 13 Network participants in a TCP/IP (Internet) based network structure are addressed via IP Addresses, but as you can see a network participant can offer for example different services. To address different services at a network participant using a singular IP Address there is a subordinated identifier called port. The port is specified by a number between 0 an 65535. Ports between 1 and 1024 are so called “well known ports”, which means that in the internet exists a common assignment of services towards these ports. For example 21 is commonly used for FTP, 80 is commonly used for http (web). This association is not a must. The port associated with a service can be changed. The other communicating party then must specify the port number explicitly, if it differs from the common principle. Such a change of port numbers makes sense if a network participant wants to offer two different services of the same kind using the same IP Address. 14 Port forwarding names a process where a router using NAT associates a port of the external IP Address to a port and IP Address of an internal network participant and forward all traffic from outside destinated towards that particular external port towards the defined internal IP Address and port number. 15 NAT is an acronym for Network Address Translation. Most internet access routers at home are using this technique. It is used when a router has just one public IP Address for accessing the internet but has to connect several computers of a private network. So the router maps all traffic from the inside of the network to a singular external IP Address by changing the port number. It therefore uses a mapping list associating the internal IP Addresses and port of a network communication with an external port. This list is dynamic and the associations are deleted after a certain period of time. A network participant from outside therefore can’t address an internal one if the communication hasn’t been initiated from the internal partner.

46

Manual IB-NAS4220-B

Guest Access Setting

By default the IB-NAS4220-B has a preconfigured account for guest access respectively anonymous access. This means that via Windows share and FTP there is a guest folder/share which could be accessed anonymously without a user/password authentication.

Attention: Leaving the guest access enabled means a high level security risk when the IB-NAS4220-B is exposed to the internet or any public network. This can lead to malicious abuse. If you expose the IB-NAS4220-B to any public network, it is strongly recommended to disable the Guest Access.

The reason why the default setting is enabled is to ensure that the IB-NAS4220-B is readily accessible when used the first time.

In addition to enabling and disabling that feature a quota for that account could be defined for restricting the quantity of disk used by users accessing the IB-NAS4220-B via guest settings.

Attention: To be able to set a quota the EXT3 file system has to be chosen for the data partition, because only the EXT3 file system supports that feature. If the data partition is formatted with EXT2 or FAT32, this option can not be selected.

Share16 Management

In this section of the web management surface is defined how the HDD storage is offered to the network. Here you can create folders, so called shares, and define the access rights for the different users or groups towards it. For each folder created here the Windows (Samba), FTP and NFS Access can be defined and restricted.

The share management could be found selecting:

16 The terminology “share” is used for HDD folders made accessible to the network. This terminology is just used in the Windows/Samba and NFS context. FTP does not use shares to structure the storage offered the Network. How a share is made accessible to the operating system on client side depends on the operating system. At Windows and MAC each share is integrated in the local storage treatment like an own drive. Linux integrates in its directory structure at a defined mounting point. The folder exposed as share is then visible and usable with all it’s contend (directories or files) as an own drive respectively directory.

There are two major ways of defining the access towards a share. The first is to allow access for all. Then no access control takes place on the share and everybody can read, write or even delete data on the share. The second is to define the access rights on user and group level. There are two different access rights you can give to a user or a group of users: “Read Only” and “Writable”.

User/group right Description

Read Only The user is only allowed to read or copy a file or directory on the share

Writable The user is allowed to read, write or delete a file or directory on the share and also to create new files or directories

Network Service The IB-NAS4220 offers a variety of other Network services such as sharing Pictures, Music and Videos to the local network, DHCP or Downloading/Sharing files over the internet. The following Table gives you a quick overview:

Network Service Description

DHCP A DHCP server allows configuring all network devices in a subnet automatically and centralized.

Bonjour Bonjour is a protocol, which broadcasts a list of services to other network devices. These devices can than recognize automatically the services offered by the IB-NAS4220-B. Mac computers use this protocol mainly.

iTunes support This service offers all music and video content stored in the directory “music” of the “public” share to all iTunes programs in the local network.

BitTorrent protocol support BitTorrent is a protocol, which allows sharing files via the internet. It is used for example to share open source project files. Please mind copyrights when sharing files! Sharing of copyright protected data without permission is illegal. It might lead to severe punishment!

Twonky Media A UPnP-AV17 server, which allows to broadcast music, picture and video content to network media players in the local network. Twonky Media is integrated as 30 days trial version and can upgraded to a full version by simply purchasing a license from Twonky Vision.

17 UPnP-AV is a standard introduced by Microsoft to allow home entertainment devices to communicate and distribute music, picture and video data over a local network. By using this protocol a network media player connected to a TV might be able to access these data stored on the IB-NAS4220.

58

Manual IB-NAS4220-B

DHCP Server

A DHCP Server allows centralized configuration of all network devices which are set up to automatically detain an IP-Address. A network device, which has been set to auto configuration, looks for a DHCP server during start up and asks this server for an IP-Address. In a home network this service in most cases is provided by the internet access router (for Example a DSL router). Having two DHCP servers active in a network is possible but only recommended for professional computer users, knowing exactly what they are doing.

Attention: Having two DHCP services run in the same network can cause network failure. Anyone, who does not know how to configure two DHCP servers correctly, should better deactivate the DHCP Server function of the ICY BOX, if there is already a DHCP server in the same subnet.

Automatic DHCP configuration

When the IB-NAS4220-B is configured to automatically obtain an IP-Address by DHCP and it can’t find a DHCP server when starting up, the IB-NAS4220-B assigns itself the IP-Address 192.168.1.1 with a subnet18 mask19 255.255.255.0. It also activates automatically its DHCP Server, distributing IP-Addresses from 192.168.1.2 to 192.168.1.50 with a Maximum Lease Time of 1 day. This behavior ensures an easy auto configuration of the IB-NAS4220-B in a Network with no auto configuration infrastructure.

18 TCP/IP based networks, as the internet, are structured into different network parts called subnets. A subnet is built by a set of IP Adresses all having the same digital beginning. Remember: an IP Address is always interpreted as 32 bit binary number containing 32 binary digits. IP Adresses of the same subnet all have the left part of these digits in common. How many of those digits are used to define a subnet is described by the net mask. Computers in the same subnet are able to communicate directly together. Computers in different subnets need a so called router which connects different subnets and forwards the net traffic from one subnet into another. 19 The net mask defines which part of the IP Address is describing the subnet. Together with the IP Address it is the minimum necessary part of the network configuration. So it always has to be set appropriate.

20 In a TCP/IP based Network a computer can send directly data only to other computers in it’s own subnet. To be able to send data to other computers, a rooter is necessary to link this subnet to the rest of the network and all computers in the subnet need to know its IP Address because they will send all data for destinations out of their subnet to the rooter to be forwarded. This IP Address of the router is defined by the default gateway setting. 21 DNS is the acronym for “domain name service”. This names a process of assigning internet names to IP Addresses. The DNS server is comparable to a telephone book. At this server all internet applications look up the referring IP Address for an internet name. Without that service or when the DHCP server doesn’t know the internet name, the internet name could not be used to address a host or device. The only chance to get access to that host or device is to use the IP Address directly.

DHCP Setting Description

DHCP IP Address End End of the IP-Address range.

Maximum Lease Time Maximum period of time in which the distributed IP-Address is valid. Clients normally try to update the IP-Address at half of this time. The longer this period is the more likely it is that the DHCP server runs short with addresses.

Bonjour (including iTunes support)

Bonjour is a protocol to distribute service information among network devices. This protocol is mainly used by Mac computers. Enabling the support of this protocol simplifies the use together with Mac computers. If Bonjour is enabled, the iTunes support could be enabled too. The iTunes support distributes the content of the “music” directory in the “public” share to all iTunes programs in the local network. So if iTunes is enabled, the content of the “music” directory in the “public” share can be played directly using iTunes on any computer in the network.

To activate these services select:


Bonjour

BitTorrent protocol support

The BitTorrent22 protocol is used to share files over the Internet. A lot of scientific and open source projects are using this service to distribute files in the internet.

The settings for the BitTorrent protocol support can be found selecting:


Bonjour

Basically the network traffic created by the BitTorrent protocol can be limited.

Attention: Setting up the BitTorrent protocol will cause constant internet traffic and this might lead to a permanent internet connection on some router configurations. This can cause high internet costs at some internet rates. So please make sure that you are using an appropriate tariff like a flat rate.


Setup bandwidth limitations for outgoing (up) and incoming traffic (down) here

To download certain data you need to upload its referring torrent file.

Attention: The technique of BitTorrent automatically causes an upload of the files you are downloading again. So please mind any copyrights of data you are downloading. Distribution of copyright protected data without permission is illegal and might lead to severe punishment. Also RaidSonic forbids you to use its Firmware to do so, by its license herewith.

22 By using the BitTorrent protocol it is possible to share and download files without a centralized server. These files are divided into small portions which are then copied from client to client directly. So each client acts as a server too. Small portions downloaded from a client can be transferred to another client immediately. This principle makes the protocol so interesting for the educational sector, which is always short of server space.

Twonky Media

The IB-NAS4220-B includes a 30 days trial version of the Twonky Media server. The Twonky Media server is a UPnP-AV server. UPnP-AV is a protocol which allows network media players to communicate with the IB-NAS4220 and access media content stored on the IB-NAs4220-B, such as music, pictures or video.

Install Twonky Media

The Twonky Media server is not part of the firmware of the IB-NAS4220-B. So it has to be installed on the IB-NAS4220-B first. The reason why Twonky Media needs to be installed on the IB-NAS4220-B is, that Twonky Media will be updated several times a year. This will be done because Twonky Vision adapts this media server to various new media players each year. In order to keep you up to date you can download the latest Twonky Media Version from the RaidSonic Homepage:

http://www.raidsonic.de

To install the twonky media server you simply have to copy the “twonkymedia” directory with all subdirectories to the “applications” directory of the “public” share. You can find a Twonky Media version on the CD-Rom, which is part of the delivery of the IB-NAS4220.

If you download the latest version of Twonky Media from the homepage mentioned above you might have to unpack the downloaded file first to disk of your local computer and then copy the resulting “twonkymedia” directory to the “applications” directory in the “public” share of the IB-NAS4220-B.

USB-Sticks and USB hard discs The IB-NAS4220-B can be extended with external USB mass storage devices, such as USB-Sticks or USB hard discs. The IB-NAS4220-B so far supports up to 2 external storage devices, since it has 2 USB 2.0 interfaces. If one of these interfaces is already used for a USB Printer the IB-NAS4220-B supports only one USB mass storage device.

Supported file systems

As on the internal hard discs the IB-NAS4220-B supports EXT2, EXT3 and FAT32 on external mass storage devices. The IB-NAS4220-B supports only one partition per mass storage device. If the mass storage device has more than one partition, only the first partition will be recognized.

USB access via Network

If any USB mass storage device with a compatible file system is attached to any USB interface of the IB-NAS4220-B it will automatically be recognized and a share containing the fist partition of the external USB mass storage device will be created and presented to the network without any password restriction. The name of the share is “usb<number>”, where <number> is a number counted up from 1 in the chronological order of attachment. So the USB mass storage device, which is attached first will become the share “usb1” and the second “usb2”.


One Touch Backup

The first partition of the mass storage device attached to the front USB interface can be backed up to the internal disk of the IB-NAS4220-B at pressing only one button. To do so, just follow these steps:

1. Attach the referring USB mass storage device to the front USB port.

2. Press the OTB (One Touch Backup) button in the front for at least 2 seconds.

3. The content will then be copied to a directory in the “public” share which will be named “backup-<DATE>”, where <DATE> is the date of the backup.
